Note that you will not be able to hibernate without the resume hook, if you are using the classic hooks in the mkinit. If you do not use hibernation it is ok, if you use it you may want to check if you are on the newer systemd hooks (which are now the defaults and you have another pacnew for the mkinitcpio.conf file).

Your hooks can probably look like this, if you do not use encryption
HOOKS=(systemd autodetect microcode modconf kms keyboard sd-vconsole block filesystems fsck)
